'ERNST A. KELLOGG AND IYILLIAM IV. COX, OF KANSAS CITY, MISSOURI.

AUTOMATIC CABLE-RAILWAY CROSSING.

SPECIFICATION forming part of Letters Patent No. 442,704, dated December16, 1890.

Application tiled March 17, 1890. Serial No. 344,160. (No model.)

To all whom 25 Wray concern:

Be it known that we, ERNST A. KELLooc and VILLIAM W. COX, of KansasCity, Jackson county, Missouri, have invented certain new and usefulImprovements in Automatic Cable-Railway Crossings, of which thefollowingis a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

Our invention relates to improvements in street-railway cable-crossings;and it consists in the particular construction and arrangement ofdifferent part s, hereinafter more fully set forth and described byreferring to the drawings by corresponding letters.

The object of our invention is to provide a means by which the gripattached to a gripcar on tracks running in two different directions maysuccessfully cross each other without the grip coming in contact withthe cable running in the opposite direction. In this ease we have showntwo sections ot cable railways crossing each other in the oppositedirection, we will say one running east and west and the other north andsouth. To accomplish this end we have provided an automatic arrangementwhich we will call a gipsy, that is so arranged with its upper portionresting immediately under the slotrail of the track running north andsouth, and. so constructed that when the cars are passing on the tracksruiming east and west the grip comes in contact with the gipsy, pressingit downward, carrying the cable on the north and south line with it,thereby letting. the grip pass free and clear over the cable. iVhen thegrip passes off of the gipsy and over the north and south cable, thegipsy by means of a spiral spring on its under side and sufficientweights attached to the rear of the gipsy readily forces the gipsy backto its normal position.

Figure l is a plan view of two street-railway tracks crossing each otherat right angles. Thetrack running east and west, it will be observed,has an abrupt parallel lateral offset formed on each side of the trackrunning north and south. This offset is made in these tracks for thepurpose of throwing the grip and car out of its main line, in order thatthe grip may pass free and clear by the pulleys. (Seen in the dottedlines at Fig. l.) Just before the car reaches the offset in the trackthe cable is dropped from the grip. The ear then passes with its ownmomentum over the crossing, the grip at the same time coming in contactvwith the gipsy, which forces the cable of the north and south track downout of its course, thereby passing free and clear over the cable.

' Fig. 3 is a sectional View showing the position of the east and westline and crossing ot' the north and south line with the lag-pulleys inposition holding the east and west cable from coming in Contact with thenorth and south cable. It will be observed that in this view we haveshown a lag-roller attached to the under side of the gipsy to destroythe greater part of the friction which would be otherwise caused by thegipsy coming in contact with the cable.

Fig. Il is a cross-sectional view of the roadbed, showing the locationof the gipsy under the slot-rails. In this viewit will be seen moreclearly the position of the weights K K, attached to the rear of thegipsy near each edge, with the cable I passing between them.

A, Fig. l, is the tracks running north and south. e is a slot-rail; C C,the slots running east and west. G G are two small pulleys (shown in thedotted lines) over which the cable passes.

Fig. 2 is a side view of the grip-car, showing the position of the gripin passing over the gipsy; d d, the top ends of the lever by which thegrip and brakes are operated. B is the car. D is the grip. C is theslot-rail; e, the slot-rail running north and south; GG, a small pulley;g, the wrist; K, the Weights in the rear of the gipsy; Q, the yokes inposition; J, the gipsy; j, the lower portion of the gipsy; P showing theposition of the lower end of the gipsy bolted to the cross-beams O O. Lis the spiral spring; M, lag-roller; N, cable running north and south;l, cable running east and west; E, large lag-pulley located between thetwo tracks running north and South. (Seen at dotted lines in Fig. l.)

In Fig. 4, C is the slot-rails; R R, trackrails; J, the gipsy; N, cablerunning north and south; i, the lower portion of the gipsy; K K, theweights; F, the wrist holding lag- IOO pulleys in position; O,cross-beams to which the gipsy is secured; Q, the yoke; E, thelagpulley, and I the cable.

Fig. 5 is a detail View of our gipsy, showing its construction. The twoWeights in the rear and the spiral springs L L are attached to thebottom of the section.

Having thus fully described our invention, what we claim, and desire tobe protected in by Letters Patent of the United States, is-

In a crossing for cable railroads, the combination, with two tracksintersecting each other, of cables passing under the said tracks, alag-roller around which one ot the cables is carried down, a gipsypivoted beneath the said cables and extending above both of the ERNST A.KELLOGG. l XVILLIAM \V.
